The Student Investor Challenge is a UK-wide stock market simulation for students aged 14-19, run for many years by The London Institute of Banking & Finance and peaking at more than eight thousand teams. Teams of four are registered by a teacher.
In round one each team runs two virtual portfolios of 100,000 pounds: an Active Investor book traded daily, testing reaction to news, and a Strategic Investor book with capped monthly trades, testing longer-horizon allocation.
Prices come from live London Stock Exchange data, and an unusual rule applies a 1,000-pound daily Windfall Tax whenever either book holds more than 15,000 pounds in cash, mimicking the pressure on a real fund not to sit idle.
After round one, 500 UK teams enter a four-week online semifinal that switches to forecasting: each week teams predict Friday closing prices of selected assets, scored on accuracy and holding duration, with the best three of four weeks counting. The top eight attend a live final in London, where the winners and their teacher earn a week-long educational trip to New York.
One organizational caveat: LIBF renamed itself Walbrook Institute London in 2025, its former competition page now redirects to walbrook.ac.uk without competition content, and the challenge material now sits at studentinvestor.org, so confirm this season’s dates with that site directly.
